Approval Certificate No. 07-0124-02) Class 1 or 2 according to IEC 60651:2001 and IEC 60804:2000 ½” microphone UC52 (or UC52/1) condenser type, pre-polarized, for free field Dynamic range 30 dBA ÷ 143 dB Peak Linearity range 80 dB Acoustic parameters Spl, Leq, LeqI, SEL, LEP,d , Lmax, Lmin, Lpk, Dose, Ln Frequency weightings Simultaneous A, C, Z (only C and Z for Lpk) Time weighting Simultaneous FAST, SLOW, IMPULSE Integration From 1s to 99 hours with Back-Erase function Statistical analysis It displays up to 3 percentile levels, between L1 and L99 Probability distribution and percentile level calculation from L1 to L99 ( HD2010.O2 “Advanced data logger” option) • Parameter: LFp , Leq, Lpk , A, C or Z - weighted (only C or Z for Lpk) • Sampling frequency: 8 samples/second Classification: Classes of 0.5 dB Analysis of events (Option HD2010.O2) • Calculation of 5 freely-programmable event parameters • Calculation of statistical levels from L1 to L99 • Event identification trigger with programmable threshold and duration filter • Manual trigger Profile data logging (Option HD2010.O2) Parallel acquisition of profiles, reports and events 1 profile with sampling 1 /8 s and 3 profiles with 2 samples/second, 5 parameters profiles in Report mode with minimum sampling interval 1s. Display Graphic backlit LCD display 128 x 64 • 3 parameters in numeric format • Profile LAFp with 8 samples/second (option HD2010.O2 “Advanced Data Logger”) • Graph of sound level probability distribution (option HD2010.O2 “Advanced Data Logger”) • Graph of percentile levels from L1  to L99 (option HD2010.O2 “Advanced Data Logger”) Memory • Internal, equal to 8 MB for more than 500 records. If the HD2010.O2 option “Advanced Data Logger” is installed, with 8 MB it is possible to record 1 parameter PROFILE @1/8 s + 3 parameter SLM @ 1/2 s for more than 40 hours. • External, via the HD2010MC memory card interface, using SD cards up to 2 GB Input/Output • RS232 serial and USB interfaces • AC output (LINE) • DC output PC programs Noise Studio (provided with the instrument): PC interface for data download, set up and instrument management Licensed software modules to be enabled by hardware key: • NS1 - “Workers protection” module. Analysis of noise and vibrations in the workplace according to UNI 9432 and ISO 9612 and 2003/10/CE and 2002/44/CE directives. • NS2A - “Acoustic pollution” module. Analysis of environmental noise. Analysis of the noise climate and assessment of noise from road, rail and airport according to the law. (requires option HD2010.O2). • NS4 - “Monitor” module. PC based real time acquisition. Remote monitoring and data capture. Remote connection also via Modem. The program allows programming of measurements and calibrations with timer and performs events audio recording with programmable triggers levels. • NS5 - ”Environmental Noise” module: environmental noise analysis. Noise sources identification with threshold conditions and impulsiveness evaluation. Some of the functions require HD2010.O2 option.
